eral object of said invention is to provide new and improved devices of the character specified and which are especially adapted for use with a continuous folded work sheet. To the above and other ends my invention consists in the features of construction. combinations of devices and arrangements of parts hereinafter described and 'particularly pointed out in the claims.

In some kinds of commercial typewriting, notably in railroad billing, folded work sheets are employed to provide duplicate copies, -tl ese-work sheets being in a continuous, strip. For example, in billing through freight where there is an. interchange 'be-.

tween different lines of railroad, two, and

in some instances three or more, duplicate struction has heretofore been suggested in freight receipts are required. Where two duplicates are required it is preferable to provide a bill sheet folded in triplicate, that is, folded at its opposite side edges to pro1- vide three thicknesses or plies of paper. Said work sheet is preferably continuous,

being provided in a long strip which may be perforated at regular intervals in receipt lengths to facilitate the severing of the receiptsafter they have been written. It will be clear that it is not practicable to insert .ca-rbon roll carriers between the folds of; such a bill sheet and the alternative, has been to interleave continuous carbon strips with the plies of the bill sheet, the carbon strips being severed with the bill sheets, {thus I entailing considerable loss, since instead of being used repeatedly until. exhausted, the' carbon strips are used but once. A' conwhich bands of carbon have been arranged on stationary supports extending ticable, since the carbon cannot be fed or advanced with the bill sheet and will remain practically stationary opposite the printing point; besides obstructing or pres eemcatien a iiettqs Patent. n gubanun meitomber sa t-911. Serial It'd-657,140.

'be readily transversely between the folds cf the bill sheet, but such a construction is obviously imprac- 1 venting the advance of the bill sheet with which the carbon is interleaved.

' My present improvements overcome the disadvantages and defects of prior constructions by providin a carbon roll arranged vertically outside of the bill sheet, in combination with a guide having a turning bar over which the carbon having been led in between the superposed work sheets or plies of paper is turned downward at rightangles andguided between and parallel with the superposed plies of paper over and around the platen. Preferably a restoring device is also provided which rewinds the used carbon when thepaper feeding devices are released from the platen.

11 carrying. out my invention in the present instance I provide a supporting frame which is detachably mounted on the travelturning bars over which the carbon is guided inward between the folds of the bill sheet which is foldedin triplicate, the carbon strips being then turned at right angles above the platen and led downward between the bill folds until brought within the control of the platen and the feeding devices ordinarily associated therewith. The supporting frame also carries a severing device which is useful in severing the work sheets from the continuous folded strip after the data on each has been completed and after the restoring devices have rewound the carbon strips on their rolls.

In carrying: out my invention in the present instance have shown. it as applied to a Monarch typewriting machine but the nature of the invention is such that it may adapted to other styles of writing machines.

The present embodiment of my invention will be described and explained .in detail in connection with the accompanying drawings, wherein- Figure 1 is a fragmentary front elevation, partly in section, of the carriage of a Monarch typew-riting machine showing the invention applied thereto. Fig. 2 is a side elevation of Fig. 1, parts being omitted and parts broken away. Fig. '3 is a vertical sectional view taken on a plane represented by the broken dotted line m m in Fig. 1 and looking in the direction of the arrows at said line, Fig. 3 being drawn to a larger scale than Fig. 1. Fig. 4 is a diagrammatic view showing in side elevation the way in which the folded bill sheet is guided and introduced into the machine. Fig. 5 is a longitudinal 'vertical sectional view of the right-hand carbon roll carrier, its mounting and associate parts. Figs. 6 and 7 are dedetail views in horizontal section showing devices for limiting the automatic turning movements of the carbon roll. Fig. 8 is a diagrammatic plan view, partly in section, showing the way in which the bill and carbon sheets are guided relatively to each other. Fig. 9 is a plan view, partly in horizontal section, showing the severing blade or device and associate parts.

Referring first especially to Figs. 2 and 4, the lower part of the main frame 1 of the machine is surmounted by a top plate 2 above which stationary standards 3 support fixed track ways 4 which cooperate through anti-friction balls 5 with a slide bar 6 comprised in a platen carrier or carrier which further includes end bars 7, said end bars' being also connected by a cross rod or bar 8. Mounted horizontally on the carriage is a rotary, cylindrical platen 9-"which has con-. nected to it at one end a line spacing ratchet wheel 10, the latter cooperating with line spacing devices (not shown) which may be actuated to turn the platen through line space distances. Coiiperative with the front face of the platen are printing devices of.

the usual Monarch style, and which comprise, as shown in Fig. 4, type bars 10*, the type barsbeing pivoted on hangers 10" that are supported on a shiftable segment 10. Each type bar is operative by a train of devices. comprising a. link 10, a sub-lever 10 and a key lever 10.

Paper controlling devices cooperate with the platen, said devices as shown in Fig. 3 comprising a main feed roller 11 carried by spring-pressed arms 12 pivoted at 13 on brackets 14 projecting forward from1 the slide bar 6. Forward of the main feed roller is a secondary feed roller 15 carried by spring-pressed arms 16 also pivoted on the brackets 14. The main and secondary feed rollers cooperate with the platen through openings in a paper deflector 17 hung on a rock shaft 18 'ournaled on the end bars 7 of' the platen rame. Coiiperative with the platen at its front,'u per side are paper controlling devices w ich are mounted on the rod 8 and comprise each a forwardly extending support 19 on which is mounted a pivoted spring-pressed frame 20 which supports a pin 21 carrying a pressure roll 22. Lugs 23 on the supports 19 provide bearings for a rock shaft 24 to which are secured hubs 25. Fixed thereto are downwardly extending guide fingers 26 ed at 28 an armor toggle element 29 hav-- ing a finger piece 30, said arm being pivotally connected at 31 with another toggle element 32 having a fixed pivot on the platen carrier. By pulling the finger piece 30 forward the rock shaft 18 may be rocked and locked in abnormal position. WVhen rocked forward the rock shaft cooperates through lugs 33 carried by it with pins 34 on the arms 12, this cooperation releasing or throwing off the main feed roller 11 and further.

operating through rollers 35 carried by the. arms 12 to act on the arms 16 to release the secondary feed roller 15 and the deflector 17 The rock shaft 18 is also connected with the rock shaft 24 by devices comprising crank arms 36 and 37 and a connecting link 38, the crank arm 36 being fixed to the rock shaft 18 and the crank arm 37 to the rock shaft 24, the latter being rocked oppositely from the rock shaft 18 by the connecting devices aforesaid. .'The rocking movement of the shaft 24 operates to release the guide fingers 26 and further to release the pressure rolls 22. The release of said pressure rolls is effected through arms 39 rigid with the hubs 25 and bifurcated at their lower ends to embrace the pins 21. *The paper controlling and releasing mechanism above briefly described will be found set forth in greater detail in my pending application Serial No. 539,954, filed January 25th, 1910 to which reference may be had for fuller ex lanation.

y novel carbon roll devices are mounted on a frame which is .detachably supported on the traveling carriage of the machine. Said frame is shown clearly in Figs. 1 to 3 and comprises side or end plates 40' which are connected near the; top and also at the middle by pairs of cross or tie rods 41, said rods being threaded at their ends to accommodate nuts 42, each end having a pair of nuts, one outside and one inside of the associate end plate. Each end plate is provided near its lowerend with an inwardly extending hub 43 which fits over the frame rod 8 and may be secured thereto as by a detachbetween the 1,080,239 lit plate 40, said arms being'splayed at their upper ends and clamped to the outer face of the associate side plate by the lower outer nuts 42. Thence the arms 46 curve outwardand downward and their lower ends are splayed or flattened, the fiat ends bein brought together and securely clampe against'the platen frame 10' the screw 47 which assists to hold the vro 8 in place.

The supporting frame above described is comparatively llght but is stron' and although readily attachable to and etachable from the carriage, is, when secured in place, quite rigid on its supfport. In order,

to detach or dismount said ame' it is only necessary to unscrew the screws 13 and to detach the rod 8 by unscrewing the screws 47. Mounted'on the detachable frame comprising the end plates 40 and tie rods, 41 are two carbon supply rolls one being vertically disposed outside of each end plate at right angles to the length of the platen. .The details of the right-hand supply roll and its support are illustrated in Fig. 5 and since the left-handsupply'roll is of like construction and mountingthe following description of the right-hand roll and associate devices is 1tio be understood as applying to both the ro s.

A U-shaped bracket 48 is secured b 'a screw 49 to the lower part of the end ate .40 and extends laterally outwardthere mm,

the parallel horizontalrarm s of said bracket providing a lower support for the carbon roll. The upper support therefor is provided by a pivoted bracket 50 which, as shown in Fig. 2,. is pivoted on the outer end of the rear upper tie rod 41, being confined late 40 and the outside nut 42. The forwar portion of the bracket 50 is slotted at 51 to fit over the end portion of the forward upper tie rod 41 between the outside nut 42 associated therewith and the plate 40, and said bracket terminates in a finger (piece 52 by which it may be swung upwar on its pivot from the 'Fig. 2 .po-

sition wherein it is kept inplace by the nuts 42. The swinging bracket 50v is provided with a latera plate or car 53. A bushing 54 is secure between the arms of the lower bracket 48 and providesa bearing for a shaft 55, the lower end of said shaft being reduced at 56 to take up end thrust against the lower arm of the bracket.

57 indicates a plug that is reduced to receive the lower circular flange 58 of the roll holder and has a driving fit into the lower end of a tubular core 59, the opposite plug 60 secured in place by a pin 61. The shaft terminates within a bearing opening in the plug 60 and its top is provided with a slot 62 to receive a screw driver for adJuSting purposes, as hereinafter described. The

horizontal off-set bearin lower end of the shaft is secured to the bushing 54 by a set screw 63.

The duplicating material or carbon sheet 64 is wound in a roll on a tube or core 65 of paste-board or the like which is slipped down over the tube 59and frictionally engages therewith. The core 65 projects slightly above the'top of the carbon roll and receives the hub 66 of a flange 67 the flanges 58 and 67 constituting spool heads and being spaced apart by the core 65 far enough to provide clearance for the carbon roll 64. The upper flange 67 is clamped in place by a shouldered thumb screw 68, the shouldered portion 68 thereof bearing r0- tatably in an opening in the stationary bearing plate 53 and also engaging clamp-wise with the top of the flange 67, said thumb screiv passing through the hub 66 and its lower end being threaded into the plug 60, the upper end of the opening 60 thereof being tapped for the purpose. By screwing down the thumb screw 68, the core 65 is pressed or clamped between the two flanges or heads 67 and 58 and becomes rigid therewith and with the inner core 59 so that the carbon roll can turn to unwind the carbon only when the carbon'holder or carrier rotates as a whole, said holder comprising the cores 59 and 65, the flanges 58 and 67 the plugs 57 and 60 and the thumb screw 68. It will be understood that when the thumb screw 68 is removed the bracket or lever 50 may be swung up and the carbon roll, together with the outer core 65, readily removed from the machine. The shaft 55 is held from turning by the set screw 63,and a collar 69 is pinned or otherwise secured to the shaft above the plug or bushing 57 to prevent vertical displacement of the carbon 'roll holder while at the same time permitting rotation thereof on the shaft as a stationary axis. Coiled around the shaft 55 within the inner core 59 is a closely wound spring 70 having its lower .end securedto the shaft and its upper end engaging in a vertical opening 71 in the plug or bushing 60. The tendency of .the spring is constantly to turn the carbon roll holder oppositely from the direction in which it rotates when the carbon is being drawn off and fed around the platen; that is to say, the advance or delivery movement of the carbon winds the spring 70. To vary the initial tension of said spring the set screw 63 may be loosened, the thumb screw 68 removed and 'a screw driver inserted downward through the opening 60 to turn the shaft 55 to wind or unwind the spring to the required tension, after which the screw 63 may betightened to lock the shaft. Since the spring 70 is always under tension it is necessary to provide stop devices to limit the winding-up operationof the roll when the advance end of the carbon paper is released or freed. For this purpose the lower portion or flange of the plug or bushing 57 is formed with a single tooth 7 2, best shown in Figs. 6 and 7, said tooth being adapted to engage normally in a depression 73 formed in the periphery of a broad tooth 74 on a gear 75 which is further provided with a plurality of narrower teeth 76, said teeth being spaced apart to provide openings 77 in which the tooth 72 may engage. As herein shown, there are eight teeth 76. The gear wheel 75 rests on the top of the upper arm of the bracket 48 and bears on a shouldered screw 78 which, as shown in Fig. 5, is secured to said upper arm by a nut 79. Preferably the gear wheel or toothed disk 75 is so mounted as to develop suflicient friction against its support to prevent accidental or too free rotation. The normal or initial position of the toothed members or stop devices 75 and 57, 72 is shown in Fig. 6. It will.be understood that the tension of the spring tends to turn the tooth 72 in the direction of the arrow in Fig. 6 but rotation is prevented by the tooth 72 engaging with the depression 73 and interlocking with the gear wheel 75. When the carbon paper 64 is drawn from the roll the tooth 72 will be rotated oppositely from the arrow in Fig. 6 and after it has nearly completed a revolution will engage with the upper side of the broad tooth 74 and will turn the latter downward far enough to enablethe tooth 72 to clear it. This turning movement will bring into the path of the tooth 7 2 the first of the narrow teeth 76 that is above the broad tooth 74 so that during the next revolocked by engagement with the depression 73 and thus lockingth'e carbon .roll against further unwinding rotation. Thus it will be seen. that the carbon roll may turn through substantially nine complete revolutions from its initial position before it will be locked against further unwinding movement. The number of revolutions will depend on the number of the teeth on the gear wheel and this may, of course, be varied to suit the occasion ;-but it will be found that nine revolutions are sufiicient to permit the advance of all the carbon that is-necessary for the printing of a freight bill even when the diameter of the carbon roll has been re duced to the limit.

As shown in Fig. 8 the two carbon sheets 64 are drawn off from the back of their recured to the inner faces of the end plates 40 back of the slots 80. The guiding devices 81 and 82 are preferably made of sheet metal and may be cut out as shown in Fig. 1 to reduce weight. Said devices are triangular in shape, the device 81 having its upper edge inclined downward .and leftward to provide a turning bar 84, the device 82 being provided with an oppositely inclined turning bar 85. The device 81 terminatesat its lower left-hand edge in a tongue or finger portion 86 while the device 82 is provided at its right-hand end in a corresponding tongue 87, said tongues acting to guide the work sheets and reproducing strips into the control of the'platen and its paper feeding devices at the rear side thereof. The hubs 43 are flattened so as not to interfere "with'the' guiding tongues 86 and 87. As clearly shown in Fig. 1 the carbon paper or duplicating material is drawn off the carbon roll horizontally inward toward the middle of the machine and over the front of the associate guiding device and then is deflected downward at right angles over theturning bar, passingbehind the same and being directed thereby toward the platen at its introductory side. The two carbon sheetsare thus ided close together and downward. behin their below the place at which the main feed roller w i 11 engages the platen.

As heretofore stated the present form of 120 my invention is adapted to a bill sheet folded in triplicate. 'Such bill sheet is illustrated in Figs. 4 and 8. In Fig. 8 which diagram-2' matically illustrates the folds of the bill sheet as interleaved with thecarbonsheets -64, the bill sheet is shown as comprising a rear ply 88, a middle ply 89 and a front ply 90, the rear and middle plies being joined at their right-hand edges .by a bight or fold 91 and the middle and front plies being joined at the left by a fold 92. Referring to Fig. 4,

ing three-ply lengths 94 equal to the length,

of the freight bills, these lengths usually containingpri-ntedforms. It will be understood th at the transverse folds 93 include the,

three plies extending lengthwise-of the bill sheet, although'it has not'beerr thought necessary toillustrate the three plies in Fig. 4. Of course, the manifold-work sheets may be three separate superposed continuous strips instead of three connected strips but the connected' form is preferable Thus folded transversely the continuous manifold sheet is placed in a receptacle 95 behind the type-' a writing machine, passing upward behind said machine and over 'a suspended guide roller 96 and thence downward to the machine, passing over the guiding devices 81 and 82, said guiding devices separating the plies of the sheet as clearly appears from Figm 8. Referring" to this figure it will be noted that the rear ply 88 passes downward behind the guide 82 and that interposed be-' tween the back of said guide and the front of said ply is the vertical portion of the lefthand carbon sheet 64, the same being indicated by a dotted line; The middle ply 89 passes downward, between the two guides 81 and-82, the vertical portion of the right-hand. carbon strip 64 being interposed between the front face of said ply 89. and the rear face of the guide 82-, The forward ply 90 of thework sheet passes downward in front-of and over the guide 81. The guides, it will be seen,- first direct the carbon paper inward transversely of the work sheets and then downward lengthwise thereof and interleaved between the longitudinally extending plies or folds of the bill sheet. Thus the work-sheets as brought within the control of the platen feeding devices comprise five thicknesses superposed one on the other, three-work sheets andftwo carbon or reproducing sheets, the work sheets and reproducing sheets alternating,-the outer work sheet or ply being'adap'ted to receive the type impressions. from the regular ribbon of the machine, the middle ply receiving im ressions from the front carbon strip an the rear ply or work sheet receiving impressions from the rear carbon strip. In-order that the carbon strip may cooperate with the proper plies the carbon .is wound in rolls with the carboned face outward. Provision is thus made for manifolding three copies at a single printing operation.

It will be understood that when the work sheets have been brought within the control of the main feed roller, subsequent rotary movementsof. the platen willadvance the thicknesses or plies together, the work sheet being drawn up'from the receptacle 95 and downward over the guide 96 and the carbon upward behind the forward of an inclined guide plate 107 being drawn ed from the supply rolls and inward and then at right angles downward over'theguiding. devices or turning bars. After a freight bill has been completed and it is desired torestore or'retract the carbon paper so that the used portion may be again employed for reproducing copies of the next'following bill, the finger piece 30 may be pulled forward, releasing the various paper feeding devices "as hereinbefore explained and permitting the "restoring springs 7 Oto retract the carbon paper. Durin this operation the work sheet may be he d by itsifoutg' flap or otherwise to prevent any friction from the backward moving carbon paper from retracting said Work sheet. -During the turning movements of the carbonpaper the stop or tooth 72 will rotate backward, co-acting with the teeth 76 of the toothed stop gear 75, turning said gear backward also; and this backward movement of the stop devices 72 and will continue until they reach the locking position showrrin Fig. 6, thus locking the carbon roll from further backward turning movement and limiting the rewinding of the carbon paper on said roll. After'th'c carbon paper has been retracted, the work sheet may be severed at one of the folds 93 and this may be accomplished by severing devices comprisinga U-shaped plate composed of side arms 97 and a narrow conneeting cross bar 98,-the side arms having downwardly extending cars 99 which are secured by screws 100 to the outer faces of the end plates 10. The forward portions of the plate-like. side arms are curled to embrace pivot pins 101, said pins projecting inward beyond said side arms and providing bearings for-a pivoted severing blade 102 having a forwardly extending finger piece 103 and a beveled rear edge 104, the forward edge of the cross bar 98 being beveled to correspond thereto. The pivoted de-' vice is maintained in the normal position shown in Figs.'3 and 9 by a spring 105; and v at this time the cross bar 98 and the cutting edge 104 are separated so as to provide a slot-way 106'throu h which the work sheet is adapted to be fe said work sheet passing aper fingers 26 and which is secured to the side arms 97. When it is desired'to sever one of the work sheet sections the fingerpiece 103 is raised, causing the beveled edge 104' to cotiperate with the forward edge of'the bar 98 to clamp the work sheet therebetween. While thus holdin the work sheet clamped it may be turn 0 'by drawing it forward against the sharp edge 104.- of the blade 102. Thus the degviccs 9.8 and-102-co6perate both as clamping bars to clamp paper andas cutting bars to sever the same while clamped; It will be understood that when the work sheets are thus severed, each section 94 comprises three plies 88, 89 and 90, containing identical entries, said plies being connected at their opposite. side edges by the longitudinal folds or bights 91 and 92. Consequently after the triplicate or three-ply work sheet section screws 68 may be loosened to permit fresh portions of carbon to be unwound from the rolls 64. a

My present invention provides a practicable device Which may be readily attached to existing styles of writing machines and afl'ordsmeans'of economically duplicating or manifolding on continuous workl sheets, even when the said sheets arefolded, thus adding to the difficulties of handling the carbons or du licating sheets, itbeing of course desirable 1n the interest of economy to repeatedly use the carbons until they are exhausted.

.Various chan es may be made without departlng from t e spirit of my invention. Y
